When a new cam is fitted do i need to run it in as ive been told i need to hold the revs @ 2.5-3k for a couple of minutes its a standard cam.

 

i heard the same. Probably because of the oil getting earlier into the head.

Cheers

 

Ok nice one was gonna see if any of the big tuning companies doit?

 

I don't know, but the cam i got back from the tuning was covered with a kind of grease special for running in... maby they use that stuff

Cheers

 

yes you have to work harden the cam, it wont last 5 mintues unless you do it, if the car overheats do it in 2 stages

 

Hold it on 2.5 - 3k for 20 minutes to run in a cam

 

We use Graphogen on new cams. Put some on the cam-lobe and some on the base of the lifter. The car needs to NOT idle for the first 20 mins of its life. Alot of people make the mistake of running the cam in whilst sitting still. Drive the car, but just try not to let it idle. If you rev it to 2500 for 20 mins whilst not moving, chances are it will over-heat.

 

Ok thanks for the info will try and get it done this weekend together with the other stuff its an endless list vibratech mounts, new steering rack....

 

What if you're car first needs to go to a tuner? i probably won't be able to drive because it needs to be set up so i need to do it without moving?? or wont't it be a problem if i rev it to 2500 without set up?

 

I think will not do any harm if drive it on 3000 rpm just for cam run in, because you can drive it on higher rpm without boost

 

As above. You'll not be revving it above 3000rpm, so won't be a major problem if its not set up. As long as you haven't changed anything else that would seriously affect fuelling.

 

any rs turbo with a decent cooling system should not over heat standing still with the revs held at 3000rpm, the cam could be run in stages of five minutes.

There's the problem Sean, check out how many posts there have been on this forum alone about over-heating problems and you will know that MOST RS Turbo's do infact have an issue.

Why do it stationary anyway? There's no need, providing you have a quiet road to do it on.

 

i done mine in 2, 10 minute stages as said above.

lots of ways of doing things though , but i wouldnt do it on the road just out of preference

 

but thats the problem christian i think many of as would do the work at home, where there is instant access to a quiet road, alot less hassle doing it stationary if you cant run your car at 3000rpm for twenty minutes then run the cam in stages also look to improve your cooling system because i know the standard rs rad is not man enough.

what do you do if you have modified the engine completly from a standard setup and need to run the cam in?

i haven't run mine yet

on start up DO NOT LET THE CAR IDLE FOR THE FIRST TWENTY MINUTES keep the car above 2500rpm job done.

Me and a friend finally fiited cam in the freezing conditions last nite started it up and held it @ 2500 rpm took ages to warm up i noticed the engine seemed more responsive too so now its had its 25mins of run in its time to take it for a slow but steady drive around.

Thanks for everyones input

Ben

Ps i have no heating problems its got a brand new alloy rad on

 

Euhh i changed quite alot and also the fuelpump upgrated to a cosworth!
from standard engine to a +- 190 bhp.... so maby run it in by the tuner and let him do the job?

Cheers
